IMPROVEMENT IN BINDING-FOLDERS.

Specification forming part of Letters Patent No. 138,772, dated May 13,1873 application filed April 1o, 1873.

To all whom it may concern Be it known that I, ELLIOTT PENDLETON WEST,of Jersey City, Hudson county, and State of New Jersey, have invented anew and Improved Binding-Former, and I hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawing making a part of this specification and theletters of reference marked thereon, in which the same letter representsthe same thing in each figure.

Figure l represents a side elevation of a sewing-machine with myimproved bindingformer attached. Fig. 2 represents a top view of mybinding-former. Fig. 3 represents a longitudinal central section of thesame.

The object of my invention is to provide sure and efficient means ofproducing binding so turned on both edges that it will retain its formin transportation, whereby it will be marketable by the quantity tomanufacturers ready for use. It is also capable of use with asewing-machine, the feed drawing it, as fast as formed, into the mouthof an ordinary straight binder. I accomplish it by passing the bindingover the thumb or a metal former, so that it will be rounded as itpasses between the jaws of a pair of smooth pinchers, which define andnip the edges hat as it is drawn through. If employed with asewing-machine the moving jaw should be so timed as to release when thefeed goes forward and bite when it retreats. l

A is the metal guide; B, the stationary jaw; O, the moving jaw; D, theconnectingrod; E, the pressure adjusting-pin; F, its

screw; G, the tie-piece; Il, the rocker-shaft; I, the spiral spring; K,the binderyL, the presser-foot.

Operation.

Insert the strip in guide A, between jaws B and C, through binder K, andunder presser-foot L, while rocker-shaft His thrown back, which, comingforward by tie-piece G and rod D, presses jaw C against the curvilinearstrips with such force as to bend and sharply fix its edges against jawB; rockershaft H, going back, releases rod D and spring I; draws backjaw C, leaving the binding free from friction of the pinchers to bedrawn on by the feed of the machine.

The pinohers, it will be seen, may be connected with any rotating orvibrating mech anism apart from a sewing mechanism, which causes them toopen and shut.

What I claim, and desire to secure by Letters Patent, is

1. The combination of guide A and jaws B and C, when operated together,substantially as and for the purpose specied.

2. The combination of jaws B and- C and binder K, operating togethersubstantially as specified.

3. The combination of guide A, jaws B and C, and binder K operatingtogether, substantially as specified.

ELLIOTT PENDLETON WEST.
